First of all, love this software. I couldn't find any other alternative to this as I really liked how it suits my 2d model and the rigging is just right for me.

However lately I've noticed my model completely freezes when in game. But it goes back to normal when Alt-tabbing. I've looked into what might cause this to happen, so I disabled some programs open in the background that's consuming RAM. Then I tested it out again and the problem still persists. I've been streaming in this setup (OBS  -PNGTuber+ - Game) for a while now and has been working perfectly, but this issue just happened recently so I'm a bit bummed that it's causing some problems now.

Would love to know what might be the problem for this and what I can do to fix it. 

Also not sure if I can put some links to some Twitch highlights as it shows the problem there.

Thanks!

I am having a similar issue, OBS stops capturing whenever PNGtuber+ is minimized. like as long as it's up it works, it doesn't need focus it just needs to be not minimized. It's WORKABLE but very annoying, because I have to have it up on my second monitor which practically blocks me from using OBS and forces me to use a popout window for twitch chat

after playing around a bit more I was able to get it to work by having PNGtuber+ up and then dragging OBS on top of it so PNGT+ is still "UP" but BEHIND OBS. still frustrating but it works

I think it's a common thing to not minimize whatever you're trying to capture on OBS, because that's how OBS works. So you should absolutely have the stuff you want OBS to capture up in the background at all times.

My issue was when PNGTuber stops moving completely when in game, then starts moving again when alt-tabbing, and this happens when the program is NOT minimized for me.
